Will the segment reload to other historical node when one historical node fail over

Hi,

If I set the replication of segments to 1, when one historical node of druid cluster failed, will the segment on this historical node reload to other active historical nodes in druid cluster? If it will, are there any parameters to control this detecting time to reload the segments?

Thanks

Yes. The coordinator will always try to make sure all data that should be loaded is loaded. There are throttles to control how fast things replicate but if a segment is missing, the coordinator prioritizes loading that data right away with no throttle.
